can my neighbour erect a fence, higher than mine & fixing it onto my fence posts

Hi Tracy, if your fence is a boundary fence and actually runs on the boundary line then technically the opposite side to your fence is their side to use, but if you originally paid for your fence to be erected, it's still your fence and your neighbors should have asked to do what they did as you can by right, if you did pay for the original fence, is take the fence back down and theirs with it, as it's attached to yours. If your fence is set within your boundary, which a lot of people do as then they do not have to ask their neighbors for permission to erect a fence, then your neighbors should not have attached their fence to yours as the fence front and back completely belongs to you.

No, if you paid for your fence then any damage caused to it must be paid for by your neighbour.

No he can not do this , 6 ft is the maximum height can erect fencing between joint properties.

They cannot fix a fence to your fence and in most cases cannot be higher than 2 metres

No he can not fix a fence on to your fence at all

boundary fences can not be more than 2metres and in some cases you need planning permission so I would check up on it.

If you paid for your fence to be erected then if your neighbour causes any damage to your fence you will be able to ask for damages cost as it is your property, plus they should not be fixing another fence to your posts anyway. Hope this helps

Your neighbour would be requited to ask your permission and would be liable if the fence was paid for by yourself. That being said if it is on the boundary line and is the original fence when the property was built then your neighbour could technically do that

Hi Tracy, The neighbour would be required to ask your permission and would be liable for any damages if the fence was paid for by yourself. TC Woodwork
